Oh! Just realised. The first thing you should do is get Azam from RmS to step you through the process of upgrading your firmware. It's possible that the old firmware you're running doesn't do such a good job of field weakening.

But when you do, don't forget to change the Relay_Output_State parameter to 0x000d so discharge works correctly. And just in case I still haven't understood how these bits are supposed to work, please add those diodes we discussed earlier, so the precharge relay coil is energised when either the Precharge or Main outputs are on.

Glenn - it would be great to see you again! We've got a few suspension tweaks in order. A few minor compliance issues to sort out too, like re-routing the cables and finding a rigid plastic box for the auxiliary battery. Otherwise we're rearing to go!

If you want or need I can try printing one up on my 3d printer for you. Just send me the measurements you want including any mounting lugs and how thick I can make it. I have PLA and ABS or nylon (not sure how the nylon would go).
Just let me know.

Glenn - if you can 3D-print a box with a lid, 212 mm by 54 mm by 70 mm, that would be awesome. It's to fit a battery made from eight 26650 cells.
We'll try a few things in the meantime, but having that would be awesome.
Cheers mate!

I am assuming the lid is 212 mm X 54 mm ?
what about mounting lugs ? will you bolt it on or cable tie it on?
I would suggest cable ties and lugs to hold the lid on.
what diameter are the cables coming out and where, one on each end or both at the same end?

I printed a box up last night but it might be a bit overkill on thickness (4 mm thick, 80% solid), so I might do one 2mm think (lighter). That way you can choose between strong or light.
Initially I was thinking it would be outside in the open like on a normal motor bike, but since you said it doesn't need a lid I am guessing it will be inside your main battery box. I will make a lid anyway just so it looks good.
Do the wires both come out the same end or one at each end. if each end is it (your) left or right of center with end facing you?

Thought I might do a little race report of round 2 of the eFXC at Winton Raceway last weekend, thanks to team O'Hanlon Electric Motorsport

Pottz and I landed in Melbourne on Thursday morning after catching the Redeye. We drove up to Benalla and when crossing the range I recognised a familiar cloud formation, last seen in winter in Canada... Yep, it was going to be a cold weekend.

Mike arrived that afternoon so we could prep the bike for Friday practice. Varley had arrived with their bike in JP Special livery, back in black and gold. Through scrutineering (electrical and mechanical) in no time, we were ready for some laps. We had some new 1.2 mm springs in the forks, but the re-vale didn't seem to be behaving like we'd wanted it to. We are still trying to suspend a 238 kg bike on them when hard on the brakes, so it's not going to be easy, but still, the handling is a vast improvement over Round 1 at QR.

It began to rain, then hail, and possibly snow (any ice falling from the sky counts as snow if you ask me) but there were the odd dry spells where we could go out and slowly learn the circuit with the 250s and 300s. It must have been frustrating for them, as we could nearly double their top speeds in the straights but they'd embarrass us in the corners. Pottz was the only one to qualify, but at 2:38 it wasn't exactly amazing It was so good to know that our 700 volt battery powered electric bike could be ridden in the rain with no fear of electrocution or faults. We cranked the regen torque up to 80 Nm and it seemed to feel pretty good, but it was really too wet to make much use of it and test it properly. We also took the ramp rate down to 30 Nm/s for a slower throttle rate, but as it turned out 35 would have been about right.

Saturday race one was a cracker, with Danny Ripperton and Danny Pottage duking it out for first. My old lap record from Voltron 1 was smashed by ~16 seconds, first by Pottz with a 1:42.529 on lap 2, only to be bettered by Ripperton on lap 3 with a 1:42.396. Which was great to see Voltron Evo held a convincing gap until Pottz went into turn 1 a bit hot and ran off track, through the grass and rejoined behind Ripperton. He took second nonetheless. Unfortunately the Varley machine steered by Jason Morris was playing up after three laps, and had to retire early.

The track stayed cold all day, and by the time we were up for race two it was simply bitter. We turned the regen down to 40 Nm as the rear was chattering like crazy in race one, but it felt like ice out there. After a tight start Pottz had an inverter fault which called for a re-boot. This takes about 3 seconds, which is about 4 hours in racetrack time . By then the field had left so it was a case of go hard or run wide trying. The track was beginning to seep water again, and from a riders perspective it's not really confidence inspiring. Alex Pickett nearly had a shot at second place, but the straight line power of Voltron Evo meant he was pipped at the line.

Sunday morning was a tiny bit warmer - the ice was limited to shadowed puddles. After a good sleep and some more track knowledge, Pottz was feeling confident. Ripperton had a controller failure at the start line, causing him to limp around on reduced power. Pickett was riding on a dislocated shoulder but still managed to put in a 1:45.672, which is pretty amazing. Danny P took the win, putting in another 1:42.884 on the last lap. Alex came second and Ripperton third, lapped after the race end.

Race four was an interesting situation - Alex had to catch a plan from Melbourne, and if he raced in eFXC he's miss the flight. So Simon Galloway who was pitting with us agreed to a joyride. I recall some pre-race agreement about what to do with points allocation, but it clearly caused some tension afterwards - most notably cause Simon bloody near won the race! It was a great race to watch, with Pottz taking the win, Simon second and Ripperton coming third despite his controller issues. Much has been said about Galloway's performance, but Pickett was putting in some seriously fast laps all weekend, all with a busted shoulder. Sadly Varley were a non-start, with some serious electronics bugs to sort out again.

Another great weekend of electric racing, despite the very testing conditions. No-one likes mechanical issues spoiling an otherwise close race, but hey, that's racing. Voltron Evo is handling the corners pretty good for a big fatty, but with some more suspension tuning it can go faster. I have some great front and rear footage which I will put up soon. The rear is planted, and appears to have no trouble keeping traction out of turns. The front on the other hand...

Massive, massive thanks to Mike O'Hanlon for getting us on track and for funding most of this years' campaign. Also have to thank Kaneg for providing Danny with accessories like warmers, stands and break-off bits like footpegs. Danny is riding the wheels off this thing and it just keeps getting faster.

O'Hanlon Electric Motorsport were nominated for the AMCN "Best Presented" team - but the Yamaha at the end was the prettiest. The paint job was pretty nice.

When I get home I should be able to make a better video. Chris summed it up nicely, a good weekend's racing and all the riders were pushing very hard. I'm slowly learning to slow the big girl down and get her around a corner.

C'mon Chris, been waiting for you to post it.... Can't hold out any longer......

Big news for the WA locals.

Voltron-evo is back on home turf!!
We can take some stress out of the riding equasion and go out and have some fun on the big girl. Finally some important testing and tuning can be done and hopefully we can find some improvements in the setup.

But the really big news......

Voltron-evo has confirmed entry in the Weld West MCRCWA State Championships. It will be racing in club1000 against some of the fastest petrol bikes in the state.
Unfortunately because it is something new and the club is unsure of it the bike will start last and from pit lane but under the control of veteran rider Paul Cox should hopefully put in a good show.

If you want to check it out in action it will be racing Sat 4oct at Barbagallo. See here for details http://mcrcwa.com.au/ it is the last round of the state championship and there will be some close and hard racing.

Yeah, it's gonna be great. Can't believe we have to start from pit lane though. That's being really conservative. Surely we only have to do this once to see it's fast enough to keep up? I was looking forward to watching it holeshoot to the front!
